Demonstration Speech- How to detect if someone is lying

Be on the lookout for anything a person does with his/her face or in the head region in response to your question. This often takes the form of biting or licking the lips, or pulling on the lips or ears.

Grooming gestures When responding to a question, a deceptive man might adjust his tie or shirt cuffs, or maybe his glasses. An untruthful woman might move a few strands of hair behind her ear, or straighter her skirt. Tidying up surroundings is a another form of grooming gesture. You ask a question, and suddenly the phone isn't turned the right way, the glass of water is too close, or the pencil isn't in the right place.

Just to give a brief overview, the 6 ways that I will talk about are: Behavioral pause/delay Verbal/nonverbal disconnect Hiding the mouth/eyes Throat-clearing/swallowing Hand-to-face activity Grooming gestures

I won't be presenting the reasons as to why these techniques work for the sake of time, but you can obviously still use them as a way to detect if someone is lying. So, let's start:

In this speech, I'll be using information from former CIA officers, Philip Houston, Michael Floyd, and Susan Carnicero, who shared 6 ways to tell if someone's lying in their fascinating book, "Spy the Lie".

So this information that I'm going to present is coming from professional people, who have had immense practice with detecting lies.

VOLUNTEERS?

Thank you everyone. I hope you now have a better idea about detecting if someone is lying to you. Just remember the 6 steps, and you'll be a master in no time!

I'm sure most of you in this room have pondered about whether someone is lying to you; whether it's one of your friends, or your parents, or your siblings. Well, I'll provide you guys with some tips and tricks that'll help you detect if someone is lying.

The signs that someone is lying are obviously not as clear as Pinocchio's nose, but they're still there.

Hiding the mouth/eyes Deceptive person will often hide their mouth/eyes when they're being untruthful. There is a natural tendency to want to cover a lie.

Throat-clearing or swallowing If a person clears his/her throat or performs a significant swallow prior to answering the question, that's a potential indicator of a lie as well.

Behavioral pause/delay You ask a person a question and you initially get nothing. After a delay, the person begins to respond. That raises the obvious question: How long does a delay have to be before you would consider it a deceptive indicator? Well, think about it in context. If you ask a question that requires more thinking, then expect a delay; but if you ask short-answer question and if the person still has some delay, they're probably lying.

Verbal/non-verbal disconnect Our brains are wired in a way that causes our verbal and nonverbal behaviors to naturally match up. So when there's a disconnect, that could be a potential deceptive indicator. A common verbal/non-verbal disconnect to watch out for occurs when a person nods affirmatively while saying "no", or turns his/her head from side to side while saying "yes".
